In this preliminary study, plantar pressures were measured in four healthy women, during walking in highheeled shoes (3 inches
height) with 3 different shank curves described by the depth of last. The foot was divided into 3 regions (forefoot, midfoot,
rearfoot). For each region, the parameters, namely pressure-time integrals (PTI), peak contact area (PA), and peak pressure
(PP) were calculated from two stable steps of each walking trial. The PTI in forefoot region decreased as the depth of last
increased, while it increased in midfoot and rearfoot regions. The higher depth of last generated the less peak pressure in
the forefoot region in midstance phase. However, in rearfoot, the peak pressure did not significantly change (p=0.869). Because
of extra arch support with increasing depth of last, the PTI, the PP and the PA in midfoot region all increased significantly
